Apparently with the merge of i386 SMP branch we are no longer calling
apm_cpu_idle from the idle loop.

1.215.2.11 of locore.s has the following log message:

Revised (brutally hacked) cpu_switch and idle which deals with the
multiprocessor case.  Works, but Really Ugly (code duplication, eliminates
APM hooks and idle-page-zero, switches to idle PCB even on uniprocessor).
In need of rewrite..


Has anyone looked into this since that time?

SY, Uwe
